DENTAL PLUGGER.

SPECIFICATION forming part of Letters Patent No. 329,587, dated November3, 1885.

Application filed July 3, 1885. Serial No. 170,617.

To all whom it may concern.-

Be it known that I, WALTER K. MOORE, a citizen of the United States,residing at Marinette, in the county of Marinette and State ofWisconsin, have invented a new and useful ImprovementinTeeth-Pluggers,of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to a plugger designed for use in filling teeth, theobject being to combine with a plugger an air-pump for actuating thefilling-point, whereby a positive and uniform movement will be impartedto the filling-point, said air-pump being designed to be connected withand run by a dental engine, thus obviating the tiresome operation of theplugger by hand.

The invention consists in the peculiar con strnction, and combinationand arrangement and adaptation of the various parts for service,substantially as hereinafter fully set forth, and particularly pointedout in the claims.

In the drawings, Figure l is a perspective view showing my improvementsapplied to a dental engine. Fig. 2 is a detail View of the air-pumpremoved. Fig. 3 is a detail view of the plngger, and Fig. 4 is alongitudinal vertical section of the same.

In the accompanying drawings, in which like letters of referenceindicate corresponding parts in all the figures, A represents a den talengine, which is of any ordinary or wellknown construction. B representsthe base thereof; 0, the treadle; D, the band-wheel; E, the connectionsbetween the band-wheel and treadle. F represents a standard, to theupper end of which is attached mechanism for operating a dental drill.

As no novelty is claimed upon the engine or drilloperating mechanism, itis thought that a specific description thereof is not necessary.

G represents the air-pump, which consists of a cylinder having removablecaps or heads a, one of which is provided with an opening for thepassage of the piston-rod b, which carries the head d. In the other headis provided an exhaust-pipe, 6, controlled by avalve, f. Said head isalso provided with a short pipe, 9, to which the end of a flexible pipe,h,

(No model.)

leading to the plugger, is adapted to be connected. Upon the air-pump Gare provided outwardly-extending brackets H, which are adapted to fitupon standard F and be clamped at any desired point thereon by means ofsetscrews.

I represents a rod, which is removably secured to the clamping-bracketsH by setscrews j. The said rod is provided at its lower end with a loop,through which the piston-rod passes, thus guiding and holding said rodin position.

J represents a projection extending outwardly from the piston-rod, andto said projections is pivotally connected a rod, J, by a screw-pin, 70,having a smooth bearing portion for the rod to turn upon. To the lowerend of the rod K is secured a swivel-bracket, L, which is adapted to beconnected with a crank-arm, M, on the band-wheel shaft. It will thus beseen that when the band-wheel is turned the piston will be moved in andout of the cylinder through the agency of the rod K, thus forcing airthrough the flexible pipe.

N represents the plugger, which consists of a cylindrical casing, N,closed at one end by a head, Z, in which is a pipe, in, to which theother end of the flexible pipe is connected. At the other end of thecylindrical casing is a removable head, 0, having a collar,p, throughwhich the plugging-point passes, and working in a threaded opening insaid collar is a setscrew, q, whereby the drill -point may be clampedand held stationary. Upon the inner end of the plugging-point is a disk,1", and mounted on said point, between the disk 1' and inside of thehead, is a spiral spring, 8. A shoulder, t, is provided on thepluggingpoint, which is adapted to bear against the upper end of thecollar 1), and thus limit the movement of the pluggingpoint. \Vithin thecasing N is a sliding hammer or follower, O, which is adapted to beforced to the front end of the casing and strike the disk on the end ofthe plugging-point when the charge of air in the pump has been forcedthrough the flexible pipe, said pluggingpoint being retracted by thespiral spring. The air which may be in casing N in advance of the hammeror follower is forced out by the same when it advances through holes oropenings in the head 0. Upon the standard F is provided an arm or rest,P, from which the plugger and airpump may be suspended when not in use.The sliding hammer is provided on one end with a rubber disk, at, andwhen the device is to be used to fill cavities in the rear sides ofteeth the sliding hammer is reversed,so thatthe end having the rubberdisk thereon will strike against the disk 1' on the end of thepluggingpoint, said point being held stationary by the set-screw g. Inthis a plugging-point having a hooked end is employed. The rubber diskstriking the disk 1" causes the hammer to rebound, and as the drill isheld stationary the plugging-point is caused to strike in the cavity inthe rear side of the tooth.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the standard F and the band-wheel and treadleof a dental machine, of an air cylinder carrying clamping-bracketsengaging with said standard, a piston working in said cylinder, and arod, J, having a pivot for the pistonrod, and connected to theband-wheel of the dental engine,

and adapted to be operated thereby, substantially as described.

2. The combination,wit h a standard and the band-Wheel and treadle of adental engine, of an air-cylinder having an exhaust-port controlled by avalve, brackets secured to said cylinder and adj ustably secured to thestandard F, a piston-rod working in said cylinder, a rod, J, carrying apivot for the piston-rod and having a swiveled lower end adapted toengage the band or drive-wheel of a dental engine, and a rod, I,connected to the clamping-brackets and carrying a guide for thepiston-rod, substantially as described.

3. The combination of the plugger-cylinder, a plugging-point having ahooked end and a disk, a coiled spring arranged between thecylinder-head and the plugger-point disk, a set-screw working through acollar secured to the cylinder-head and adapted to clamp theplugging-point, and a reversible follower having an elastic disk,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
